Lizards live in deserts, forests, prairies, marshes, and rocky areas. Most lizards live on the ground or in trees. They are most active on warm, summer days. On very hot days, some lizards hide. Most lizards sleep through the winter. On warm days, they sometimes come out to eat. Lizards can become pests when they invade your home. Being very small they can easily sneak through vents, pipes, cracks around windows, sliding doors and other devices that lead to the outdoors.

Like other reptiles, lizards have certain basic behaviors. They seek out warmth and sunlight, so they can feed and digest the food they consume. If healthy, they will be alert to the world around them and find a receptive mate and reproduce. But there's far more to lizard behavior than a positive response to heat, light, food and sex.

Many lizards are carnivores, which means they eat meat. A typical diet for a lizard includes ants, spiders, termites, cicadas, grass hopper, cockroaches, earwigs, mole cricket, beetles, moths, grubs, flies, small mammals and even other lizards. Caiman lizards eat animals with shells, such as snails. Other lizards are omnivores, which means they eat vegetation and meat. One example of an omnivore lizard is Clark's spiny lizard. These lizards like fruits, leaves and vegetables. Some lizards are herbivores and only eat plants. The marine iguana, which lives in the Galapagos Islands, eats algae from the sea. Iguanas and spiny-tailed agamids also eat plants. Habitat Lizards are common in warm areas where cover and food are abundant.Lizards are found all over the world in almost every type of terrain. Some live in trees; others prefer to live in vegetation on the ground, while others live in deserts among rocks. For example, the Texas horned lizard is found in the warm areas with little plant cover in southern North America. The northern fence lizard, on the other hand, likes to live in cool pine forests in northern North America.

Most species are harmless to humans and some species can be kept as pets – including iguanas, bearded dragons, geckos and anoles. There are many reasons why you need to get rid of lizard’s droppings. The main reason is your health! Lizards frequently carry Salmonella that can cause serious problems in people. Salmonella infection can spread by direct or indirect contact with these pests or their droppings. One, three or four droppings of lizards often go unnoticed. But a big number of lizards’ droppings means you have a significant problem.
